In a study published online by the Journal of Substance Abuse Treatment, UC Davis researchers report that it takes at least a year for former methamphetamine users to regain impulse control. The results tell recovering substance abusers, their families and drug-treatment specialists that it can take an extended period of time for the brain functions critical to recovery to improve.

Two separate studies published in the current issue of Cell Transplantation into cardiac repair by cell transplantation have found, respectively, that the best way to deliver autologous bone-marrow mononuclear cells to the heart following a myocardial infarction was via the anterograde intracoronary vein and that bone marrow cell transplants for limb ischemia induced angiogenesis in patients failing therapy and facing amputation. The first study found higher cell retention; the second demonstrated an alternative to amputation.
Study could help target new pancreatitis treatments

Pancreatitis is often a fatal condition, in which the pancreas digests itself and surrounding tissue. Scientists have previously found that alcohol can trigger the condition by combining with fatty acids in the pancreas, which leads to an excessive release of stored calcium ions. Once calcium ions enter cell fluid in the pancreas it activates digestive enzymes and damages the cells.

Multiple sclerosis, diabetic neuropathy, and other conditions caused by a loss of myelin insulation around nerves can be debilitating and even deadly, but adequate treatments do not yet exist. That's in large part because of deficiencies in model research systems. In an upcoming issue of the journal Biomaterials, a UCF team addresses this problem with a report on the first lab-grown motor nerves that are insulated and organized the same way they are in the body.
